  • Patent number: 11968924
    Abstract: A cutting head body for an agricultural machine, such as a mower or a trimmer, is configured to receive a cutting line for cutting weeds, grass, or other materials. The cutting head body includes an inlet area having a cavity with a node location configured to receive a node of a cutting line, and an outlet area having a cavity configured to open to an exterior of the cutting head body. The cutting head body may include a first passageway connecting the inlet area to the outlet area and a second passageway connecting the inlet area to the outlet area. The cutting head body is rotatable about a rotational axis to move the cutting line. In some embodiments, the cutting head body is fixed to a rotatable shaft. In some embodiments, the cutting head body rotates about a fixed shaft.

  • Publication number: 20210185873
    Abstract: A driveline assembly for equipment, such as a tiller, includes a pair of counter-rotating bevel gears supported on a wheel shaft and rotatable relative to the wheel shaft. The driveline assembly includes a first slider gear movable between a first position in which the first slider gear is engaged with a first bevel gear of the pair of bevel gears, and a second position in which the first slider gear is engaged with a second bevel gear of the pair of bevel gears. When the first slider gear is engaged with the first bevel gear, the first bevel gear becomes operatively connected to a rotatable tine shaft to rotate tines in a first direction. When the first slider gear is engaged with the second bevel gear, the second bevel gear becomes operatively connected to the rotatable tine shaft to rotate the tines in a second direction opposite the first direction.

  • Patent number: 6296024
    Abstract: A fluid recovery sleeve, comprising a wall having an inner wall surface forming a fluid communication passage, a top surface having an opening for receiving a salvage container to be drained, and a bottom surface having an opening for receiving a recovery container to catch fluid drained form the salvage container. The bottom and top surfaces are formed from the wall. The openings provide an entrance and an exit for the fluid communication passage. The bottom opening of the sleeve is placed over the neck of a recovery container. The salvage container is inverted and its neck is placed in the top opening of the sleeve. Remaining or leftover fluid drains from the salvage container, through the fluid communication passage of the sleeve, and into the recovery container. The sleeve is preferably constructed of an elastic material to provide a seal around the necks of the containers and to support the inverted salvage container above the recovery container.
